I fill a ComboBox at runtime before showing it.
The box is empty; clicking the dropdown button shows the items, but no item can be selected.
Even when I set TopIndex to 0, the box remains empty.
What's wrong ? The ComboBox is not data bound.
It was once, but the data control was removed,
and the fields "DataField", "DataFormat", "DataMember" and "DataSource" are all empty.
